Prompt vs fine-tune

Prompt changes context Fine-tune changes weights

Agent vs chatbot

Chat replies once Agent uses tools

OCR vs extraction

OCR reads text Extraction returns fields

Speech vs speaker

Speech recognizes words Speaker recognizes person

Vision vs generation

Vision analyzes images Generation creates images

Fairness vs accuracy

Fairness checks groups Accuracy averages performance
